Sexual Mimicry in Mormolyca ringens (Lindl.) Schltr. (Orchidaceae: Maxillariinae)
Rodrigo B. Singer,Adriana Flach,Samantha Koehler,Anita J. Marsaioli,Maria do Carmo Estanislau do Amaral +4 more
TL;DR: Preliminary observations indicate that M. ringens flowers are self-incompatible, and it is expected that further research could bring to light whether other Maxillariinae species are also pollinated through sexual mimicry.
Journal ArticleDOI
The chemistry of pollination in selected Brazilian Maxillariinae orchids: floral rewards and fragrance.
Adriana Flach,Règine Carole Dondon,Rodrigo B. Singer,Samantha Koehler,Maria do Carmo Estanislau do Amaral,Anita J. Marsaioli +5 more
TL;DR: The rewardless Maxillariinae flowers were usually scented, and chemical analyses of their volatiles revealed that they were composed of mono and sesquiterpenoids.
Journal ArticleDOI
Evaluation of the toxicity and antimicrobial activity of hydroethanolic extract of Arrabidaea chica (Humb. & Bonpl.) B. Verl.
Luciano Mafioleti,Iberê Ferreira da Silva Junior,Edson Moleta Colodel,Adriana Flach,Domingos Tabajara de Oliveira Martins +4 more
TL;DR: Evidence is provided that HEAc is safe and can be useful in infections related to Helicobacter pylori and Enterococcus faecalis, and phytochemical analysis revealed the predominant presence of flavones and flavonols, possibly involved in the antimicrobial action of HEAc.
